I moved to a small city in the south of Chile with my wife who's also doing business remotely. You can live really comfortable here for less than $2k/mo for two people.

While we are not in a countryside yet, we bought a half hectare of land on a hill near the city and plan to build a house in a few years. I except the total cost of land + cleaning some forest + construction to stay under $150k (but we want a relatively small house).

If you are interested in moving to Chile, I made a whole site about it: https://valdiviaguide.com/
